Specification of Letters Patent.

. Patented Dec. 26. 1916.

To all whom it may concern:

Be it known that I, LoUIs L. Gonn, a citizen of the United States, and a resident of Marshfield,'in the county of Coos and State of Oregon, have invented a new and Improved Heater, of which the following is a full, clear, and exact description.

Among the principal objects which the present invention has in view are: to provide a heater to transfer heat to the incoming medium from the medium passing out of the heater; to provide a construction employingmaterials adapted for rapid radiation of the heat, and generally to provide a heater wherein the material to be heated has transferred thereto the heat units contained in the products of combustion which otherwise would be lost.

Drawinga-Figure 1 is a sectional plan view of the heater-constructed and arranged in accordance with the present invention, the section being taken as on the line 11 in Fig. 2. Fig. 2 is a vertical section taken as on the line 2-2 in Fig. 1; Fig. 3 is a detail view showing in perspective one of the sections of which the apparatus is constructed; Fig. 4 is a similar view, showing a modified form of section; Fig. 5 is a perspective view showing in detail a heating dome with which heaters of the character mentioned are provided.

As seen in the drawings, the combustion medium employed is gas. To consume the gas, a series of burners 10 are employed. The ,number and capacity of. these burners may be varied to suit the requirements of the installation. The burners 10 are preferably arranged as shown, consisting of a series of parallel pipessuitably perforated to form heating jets of suitable size and character. The gas grate formed by the pipes 10 is disposed, as shown best in Fig. 2 of the drawings, within a chamber, one

' side of which is formed by a wall 11 and the other side by a partition wall 12. The exposed surfaces of both the wall 11 and the partition wall 12 are to increase the radiating surfaceexposed to the influence of the heat furnished by the gas burners 10.

It will be understood that the purpose of the present invention is to pro-heat liquid or gas being delivered to a suitable furnace or steam or vapor generator. If the medium being delivered is water and the heater herein described is connected to the supply thereof by a pipe 13, the same is delivered primarily to the end section 14, and by means of nipples 15, to the adjacent'section ,16. From the pipe 13, the water ascends through vertically-disposed tubular passages formed by the corrugated material from which the sections are constructed, descends in the next section to be again caused to ascend, until finally delivered to the wall 11, to be thence conveyed, by a pipe 17, to its destination. If the destination is a boiler where the water is to be converted into steam, it will be understood that in passing through the present heater, the temperature of the water has been raised to a. marked degree. It will be understood that the water is thus heated by transfer or radiation, from the gases already heated, which after leaving the chamber formed by the wall 11 and the partition wall 12, pass horizontally to the back of the chamber 18, and between the wall 12 and the wall 19, and between the wall 19 and the wall 20 to a passage between the wall 20 and the wall 21 of the section 16. From the passage formed by the wall 20 and the wall 21, the heated gases move around the inner end of the wall 21, to pass between the wall 21 and the wall 22 of the end section 14. From the passage between the walls 21 and 22, the products of combustion are emitted from the stack 23 to the outside atmosphere. It will be seen that the heated gases traveling through the zigzag passages provided therefor, become cooled by transfer of their heat units to the walls of the said passages, wherein the water or other medium is traveling vertically through the tubular passages formed by the corrugated sides constituting the partitions or walls 12, 19, 20, 21 and 22.

The heater which acts in the manner described, is constructed of a series of sections, such as the sections shown in Figs. 3 and 4, and with an end wall, such as shown in Fig. 5. These sections in the wall and dome are preferably constructed from sheet metal. The sections have vertically-extending ends 24. The ends 24. are in open communication with box-like tops 25 and bottoms 26. The interiors of the tops 25 and bottoms 26 have communication through the partitions formed by the walls 12, 19, 20, 21 and 22. The partition formed by the wall 19 diifers from the partition formed by the wall 20, as-seen best by comparison of Figs. 3 and 4 of the drawings, in that the end of the partition formed by the wall 19,

adjacent the ends 24:, is omitted to form a passage 27 which, as hereinafter mentioned, allows for a freer and better distribution of the streams of heated air or gas when passing through the heater. The radiating sections are assembled so that the openings 28 formed in, the top 25 and bottom 26 register. Between the said sections and pressed within the openings 28, are push nipples 29 and plugs 30. The nipples 29 have a clear passage formed therethrough. The plugs 30 have each a small passage 31, the purpose whereof being to prevent the formation of air trapsin any of the sections or bottoms or tops thereof. By proper disposition of the plugs 30 and the nipples 29, the flow of the medium passing through the partitions in the said sections and through the walls of the said sections may be controlled. The same method of connecting the sections having the wall 12 with the side walls and top of the wall 11 is followed.

As shown in Fig. 1 of the drawings, the passages formed between the walls 12 and 19, 19 and 20, 20 and 21, and 21 and 22, may be thoroughly cleaned of all deposit. Entrance to these passages is readily obtained by opening the doors 32.

As shown in Fig. 1 of the drawings, where door-closed openings are not desired in the side wall of the heater, the ends are laterally extended to lap over the space of the intermediate section which is not structurally provided with the end, such as 24.

Claims:

1. A heater comprising a plurality of separable sections, said sections forming a boxlike continuous walled chamber, each of said sections having a hollow top and bottom, a vertical hollow end connecting the top and bottom, and a vertical hollow partition wall connecting the hollow top and bottom of each section and in communication with the interior thereof, a heating section at the front end of the heater and having a hollow front wall curved at the top, and a hollow side wall, a generator for heat de'- ,livering medium located in said heating section, the said hollow partitions being arranged in said sections to form a sinuous passage around the outside of the partitions,

2. A heater comprising a box-like chamber having continuous walls and embodying a plurality of hollow walled sections forming when united horizontally extended transverse sinuous passages disposed in a vertical plane, said sections being grouped to form vertically extended transverse sinuous passages disposed in a horizontal plane; means for circulating a heat-absorbing medium through said first-mentioned sinuous passages, said means embodyingan inlet and an outlet for said medium, said inlet and outlet being disposed adjacent the opposite ends of said passages; a heat generator located in said chamber and at the end thereof ad] acent the outlet of said heatabsorbing medium; and means for drawing the products of said generator through the second-mentioned passages for transferring the heat to said absorbing medium through the walls forming said passages.

3. A heater comprising hollow-walled front and rear end sections, the front end section forming a heat generating chamber, a heat generator in said chamber, a plurality of hollow walled sections arranged between the end sections and each having a hollow top and bottom, a hollow vertical partition formed of pairs of corrugated walls arranged between the hollow top and bottom and communicating therewith, and a hollow vertical member connecting the top and bottom at one side of the said partition, the said partitions being arranged to form a zigzag passage leading from the heat generating chamber to the rear of the heater, an outlet for the products of the heat generator leading from the rear of said passage, an inlet for heat absorbing medium connected with the bottom of the hollow rear end section, an outlet for said medium leading from the space between the walls of the hollow front end section at the top thereof, and means for connecting the several sections with each other to cause the heat absorbing medium to pass through the hollow walls of the sections from the inlet to the said outlet and for controlling the direction of flow of the medium through the said vertical partitions.
